This application is a division of application Serial No. 617.709, filedSeptember 21, 1945, which has become Patent No. 2,420,850, issued May20, 194'?.

This invention relates to a dispensing apparatus particularly though notnecessarily designed for use in connection with soda fountains fromwhich a beverage from a mixture of liquids is dispensed. In this aspectof the invention, a principal object is to provide an apparatus of thecharacter described hereinafter which will be highly efficientin use andeconomical in manufacture and of a simplified and improved construction.

A still further and equally important object of the invention is theprovision for moving the syrup eiecting piston by resilient pressure,resulting from and by reason of a spring connection between the drivingpiston and the driven piston, with the resulting structure affording apredetermined movement of the driving piston prior to the movement ofthe driven piston,

against a body of syrup previously drawn into a measuring chamber. f Yetanother and equally important object of the invention is the provisionof a dispensing apparatus of the character hereinafter described,wherein there is obtained a high volume of gas in the carbonated waterat the dispensing area, resulting` in the dispensing of a highlycarbonated drink. with the minimum amount of foam.

Stilla further obiect of the invention is the provision of an apparatusof the character hereinafter described which. by its employment, assuresa rapid dispensing of a mixed drink. usually consisting of a syrup andcarbonatedwat'er. It is common knowledge that delay is encountered inpreparing and serving a mixed drink by reason of the fact that in thedispensing of a drink consisting of a svrun and carbonated water. alarge or deep foam head results. with the conseuuence that the operatormust wait until the foam is substantially dissipated before adding tothe drink additional carbonated water and syrup tc provide a mixed drinkof proper volume. With this in mind. it is an object of the invention todispense the syrup and carbonated water in the drinking glass in amanner such that a rel- The invention consists in the novel combinaon..and arrangement of parts to be hereinafter escribed and claimed.

over this end portion of the cylinder body I4 is a cap 23 having anannular seat 24 formed therein in which a sealing ring 25 is positionedand bears against the wall plate 22. In the end portion 25 of thecylinder body I4 are threaded a'" pair of bolts 2'! which draw thecylinder body |41 l. in a direction to compress the collar IB against;
